TO ALL WHOM IT MAY-CONCERN: I

Be it known that I, JAMESSARGENT, of Rochester, in the county of Monroe, and State of New, York, have invented a certain new and useful Improvement in Securing Lock and Bolt-Shafts in Sztfelloors; and I do hereby declare that the followingis a full and exact description thereof, rei'erencebeing had to the accompanying drawings, making part of this specification.

Figure 1 isa fragment of a safe-door and a lock-case,'h aving the spindle connected therewith in my improved manner.

Figure 2, a vertical section of the same. Figure 3, vicivof a modified form of the spindle. I v Like letters of reference indicate corresponding parts in all the figures.

The locks and heavy bolt-works of safes are now almost universally operated by a spindle or shaft passing through the door, and having a knob onthe outside, by which it is turned. The great desideratum in such devices is to secure the spindle so that it cannot be drawn out or driven in, and so that gunpowder cannot be inserted around it. To accomplish this requires not only great strength and s0lidity,hut also a very nice adjustment and fitting of the parts.

My invention consists inproviding the spindle or shaft with an enlargement or swell that is embedded directly within the plating of the door, without intermediate parts, 'so that it can neither be driven in or dgawn out, and fitting so closely that powder cannot beinserted around it.

In the drawings, a burglar-proof safe is shown, made. up of altern tte plates,A A, of iron and steel. Through these plates passes the spindle or shaft B, ha ving the usual knob in, on the outside, i'or actuating it, and cam b, on the inside, for operating the lock mechanism. At a suitable position the spindle is provided with an enlargement or swell, c, which is made to fit closely in a. socket, d, ln the plating. Thus arranged, it'will be perceived that the spindle, is a fixture'in the plating, and has two shoulders or bearings ff formed to rest on opposite sides against the steel plates.

A device is already in use, consisting of a conical plug secured in a socket bored. in the door, and having the spindle resting in the plug, with a shoulder, to prevent driving-in, and a nut on the inner end, within the lock, to prevent drawing out. But there is great difiiculty connected with the use of this device. The end of the plug projects outside the safe, so that great leverage can be applied thereto; and it is, therefore, liable to be wrenehed from its socket. Leverage may, in a similar manner, be applied to the spindle enclosed by the plug; or, if the heavy blows of a sledge'are applied, the plug and spindle may be gradually driven in, so as to totally disarrangc the mechanism of the lock; If the blows are applied directly to the spindle itself, the rebound is frei' ucntly so great, and the concussion comes so angularly, that the spindle will break within or behind the shoulder,-so that the latter may be drawn out, and the remaining part easily drivenin. At anyvrate, if great strain inward orontward is applied to the spindle, great disarrangemcnt is likely to ensue to the mechanism of the lock connected therewith, since spindle is allowed a free end movement, to a certain degree, to connect from the combination wheels to the-bolt. It will be perceived that I obviate all difficulties of this kind. I

dispense with the enclosing plug by embedding the spindle directly within the plating, and there is, therefore,

no envelope which can be drawn out or driven in. The spindle is a fixture with the door itself. The shoulders or hdarii'igsfj; resting directly against the. steel plating in opposite directions, can neither he drawn out or driven in. If 'the spindle break. from the blows, it matters not whether it is in front of, or behind, the enlarge \nent; sin-3e, if it is in front, the enlargement cannot be driven through, and, if behind, it cannot be drawn out. This is a 1* "tier of very great importance, and in no other drrangement, so faras I am aware, has this efl'cet hecn aeceniplishml. The enlargement is so firmly embedded that no strain, either inward or outward, can be hroughl to bear upon the mechanism of the lock, and therefore, under ordinary circumstances, it cannot become displaced or dis-arranged. It will be perceived that the spindle for throwing the heavy bolt-work may be. arranged in a similar manner to that above described for operating the lock.

What I claim my invention, and desire to secure by Letters Patent, isi I The spindle 3. pro vided with the enlargement or swell c and bearings ff, when embedded directly in the sale without inlmmodiate parts. so as to form a fixture of the dooigsnbstanlially'as herein set forth.

in witness whereof I have hereunto signed my namc'in the presence of two subscribing witnesses.
